Local Notification with different NSDate

In my application I am going to开发者_如何学Python schedule a task to notify user at a particular date and time, for example on 31 dec. 2010 I have start time 9:00 Am and end-time 5:00 pm , and here I have to notify user 10 minutes before 9:00 AM and after 5:00 pm or sometime in between these times, like 2:00 pm so i am going to use LocalNotifications ...Am I right ? or is there any other way to achieve this .

PLease help ..

You should use LocalNotificstion only, the thing is that you should create 3 different notification so that you can achieve the scenario
